POST请求作为beego框架选项处理 [英] POST request treated as OPTIONS on beego framework

问题描述

我使用beego框架，在客户端上我的API框架和AngularJS。
我设置了所有CORS正确设置。我能做的GET请求。但是，当我尝试后，beego治疗是OPTIONS请求。它也抛出一个警告：多response.WriteHeader通话。什么可能错了吗？

I'm using beego framework as my API framework and AngularJS on the client. I have set all CORS setting correctly. I can do GET request. But, when i try to POST, beego treat is as OPTIONS request. It also throw a warning: multiple response.WriteHeader calls. what could possibly wrong?

我beego CORS设置：

my beego CORS setting:

func init() {
    orm.RegisterDataBase("default", "mysql", "root:@tcp(127.0.0.1:3306)/fakeapi")
    beego.InsertFilter("*", beego.BeforeRouter, cors.Allow(&cors.Options{
        AllowOrigins:     []string{"*"},
        AllowMethods:     []string{"GET", "DELETE", "PUT", "PATCH", "POST"},
        AllowHeaders:     []string{"Origin"},
        ExposeHeaders:    []string{"Content-Length"},
        AllowCredentials: true,
    }))

}

我ANgularJS要求

My ANgularJS request

var transaction = $http.post(BASE_URL + "transaction", transactionData);
                return $q.all([transaction]).then(function(response) {
            console.log(response);
        });

我的系统：
Ubuntu的14.04
beego：1.4.2
蜜蜂：1.2.4
angularJS：1.3.12

my system: Ubuntu 14.04 beego: 1.4.2 bee: 1.2.4 angularJS: 1.3.12

推荐答案

由于问题/ pull请求目前尚待要合并到主的可能：的问题912

That might because of an issue/pull request currently pending to be merged into master: issue 912

没有这一行，一切都很好:: router.go＃L861

Without this line everything is fine:: router.go#L861

这似乎是符合提交3bb4d6f 这说明：

// Write status code if it has been set manually
// Set it to 0 afterwards to prevent "multiple response.WriteHeader calls"

（和 router.go 不要设置状态，因此错误消息）

(and router.go do set a status, hence the error message)

提交f962457 的是应该解决这个问题，但还没有被合并。

Commit f962457 is supposed to solve this issue, but isn't merged yet.

另外问题904 提到自己无法检索会话数据$ P事$ pviously在会话引擎注册。
也许 Session.on标志可以提供帮助。

The other issue 904 mentions something about being unable to retrieve the Session data previously registered in the Session Engine. Maybe Session.on flag can help.
